I love green bean casserole and when I first started eating low carb, I though that it was a dish that could be easily converted. I found several but this is my favorite by far. I make it frequently and most people who have tried it love it as well. 


  • 16 ounces of frozen french cut green beans, cook according to directions on your package 
  • 4 ounce can mushrooms, drained well 
  • 1 small onion, sliced into very thin rings, 2 1/2 ounces 
  • 2 stalks celery, finely chopped 
  • 2 tablespoons butter 
  • 1/4 cup mayonnaise 
  • 1/4 teaspoon salt 
  • 1/2 teaspoon pepper 
  • 1/8 teaspoon garlic powder 
  • 8 ounces cheddar cheese, shredded
Step by Step: 
  1. Sauté the onion, celery and mushrooms in the butter until very soft and a little browned, about 20 minutes. 
  2. Combine all of the ingredients in a greased 1 1/2 quart casserole or 8x8" baking pan. 
  3. Bake at 350º, uncovered, 30 minutes or until nicely browned and bubbly. 

Makes 6-8 servings 
Can be frozen

My Notes:
  • It increases the carb count, but I do add a few fried onions on top.
  • I have tried Pepper Jack cheese as well and did not like the result.
